Hello,

personally, I find it very un-intuitiv that the training data has to be rebuilt with the maintenance tool. It is a good place for doing maintenance stuff all together and I would let it there. 

But from a user experience view: What about placing an option in the workflow dialog? Something like a checkbox which can be selected if I have committed several faces?
Furthermore, would it be possible to do that automatically? For example retrain after x faces of the same person have been committed.

Thinking even further: Would it be possible to retrain the network for a single person? In this case the re-training duration would also reduce. As far as I understand the functionality in the maintenance tool, it takes all recognized and committed faces and retrains all of them. My experience from my collection is that some people (~50 to 100) are often in the pictures and others (rest of ~400) appear only once a year.

With best regards

Eddie

It is important that you rebuild the training database with digiKam-7.2.0. To
do this, select the checkbox for rebuilding the training data in the face
detection/recognition section of the maintenance tool. A special album
selection is not necessary, all currently confirmed faces are used. The face
recognition works best with face rectangles, which were also detected by
digiKam. Face rectangles from other programs, e.g. Picasa or manually drawn
face rectangles, work poorly. The current face recognition can deliver over
90% correct results.
